Question: When did Latvia gain independence from where an experimental 6kV DC railway was built?
Context: Document 1: Railway electrification system: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.
Document 2: History of Latvia: The First Latvian National Awakening began in the 1850s and continued to bear fruit after World War I when, after two years of struggle in the Latvian War of Independence, Latvia finally won sovereign independence, as recognised by Soviet Russia in 1920 and by the international community in 1921. The Constitution of Latvia was adopted in 1922. Political instability and effects of the Great Depression led to the May 15, 1934 coup d'état by Prime Minister Kārlis Ulmanis. Latvia's independence was interrupted in June -- July 1940, when the country was occupied and incorporated into the Soviet Union. In 1941 it was invaded and occupied by Nazi Germany, then reconquered by the Soviets in 1944 -- 45.
Answer: 1920

Question: In Ann Arbor, who represents the assembly with the power to make immigration laws?
Context: Document 1: Plenary power: In regard to immigration law, Congress, under the Plenary Power Doctrine, has the power to make immigration policy subject to judicial oversight. The Executive Branch is charged with enforcing the immigration laws passed by Congress. The doctrine is based on the concept that immigration is a question of national sovereignty, relating to a nation's right to define its own borders. Courts generally refrain from interfering in immigration matters. Historically, the U.S. Supreme Court has taken a hands - off approach when asked to review the political branches' immigration decisions and policy - making. The Center for Immigration Studies, an organization with a slant toward isolationism, suggests there is a movement to ``erode ''political - branch control over immigration in favor of a judge - administered system and that the results have created national security concerns. The U.S. Supreme Court case Zadvydas v. Davis is cited as an example of the U.S. Supreme Court not following plenary power precedent.

Document 2: Gamal Abdel Nasser: On 5 March, Nasser's security coterie arrested thousands of participants in the uprising. As a ruse to rally opposition against a return to the pre-1952 order, the RCC decreed an end to restrictions on monarchy-era parties and the Free Officers' withdrawal from politics. The RCC succeeded in provoking the beneficiaries of the revolution, namely the workers, peasants, and petty bourgeois, to oppose the decrees, with one million transport workers launching a strike and thousands of peasants entering Cairo in protest in late March. Naguib sought to crackdown on the protesters, but his requests were rebuffed by the heads of the security forces. On 29 March, Nasser announced the decrees' revocation in response to the "impulse of the street." Between April and June, hundreds of Naguib's supporters in the military were either arrested or dismissed, and Mohieddin was informally exiled to Switzerland to represent the RCC abroad.

Question: Who was the 2017 leader of the country first to sell hamburgers outside the US?
Context: Document 1: History of the hamburger: The modern hamburger was developed in the United States, but by the end of World War II, around the middle of the 20th century, it began to spread to other countries as fast food became globalized. The main cause of this gradual globalization was the successes of the large restaurant chains. Their desires to expand their businesses and increase their profits resulted in them creating franchises around the world. McDonald's was among the very first of the burger chains to take the global establishment of its brand seriously, but it was not the only one. Wimpy began operating in the United Kingdom in 1954, 20 years before McDonald's began operation in the country, and by 1970 it had expanded to over a thousand restaurants in 23 countries. On August 21, 1971, in Zaandam, near Amsterdam in the Netherlands, Ahold opened its first European franchise. In the 1970s, McDonald's began to expand into Europe and Australia. In Asia, Japan saw the establishment of its own fast food chain in 1972: MOS Burger (モスバーガー, Mosu bāgā), an abbreviation of ``Mountain, Ocean, Sun '', which eventually became a direct competitor to McDonald's. All of its products, however, were variations on the burger adapted to the Asian world, including the teriyaki burger, takumi burger, and riceburger. In Hong Kong, Aji Ichiban competed with large chains before it spread quickly throughout Asia. One of the first hamburger vending machines debuted in Amsterdam in 1941 under the brand FEBO, its name derived from its original place of creation, the Ferdinand Bolstraat.

Question: How much debt do we have with the country where leeches began being used for blood-letting?
Context: Document 1: National debt of the United States: As of July 31, 2018, debt held by the public was $15.6 trillion and intragovernmental holdings were $5.7 trillion, for a total or ``National Debt ''of $21.4 trillion. Debt held by the public was approximately 77% of GDP in 2017, ranked 43rd highest out of 207 countries. The Congressional Budget Office forecast in April 2018 that the ratio will rise to nearly 100% by 2028, perhaps higher if current policies are extended beyond their scheduled expiration date. As of December 2017, $6.3 trillion or approximately 45% of the debt held by the public was owned by foreign investors, the largest being China (about $1.18 trillion) then Japan (about $1.06 trillion).
Document 2: Annelid: Accounts of the use of leeches for the medically dubious practise of blood-letting have come from China around 30 AD, India around 200 AD, ancient Rome around 50 AD and later throughout Europe. In the 19th century medical demand for leeches was so high that some areas' stocks were exhausted and other regions imposed restrictions or bans on exports, and Hirudo medicinalis is treated as an endangered species by both IUCN and CITES. More recently leeches have been used to assist in microsurgery, and their saliva has provided anti-inflammatory compounds and several important anticoagulants, one of which also prevents tumors from spreading.
Answer: about $1.18 trillion
